Sometimes, just thoroughly researching a single coin can make it relatively easy to make money.

A core aspect of trading is drawing lines, accurately plotting support and resistance levels on daily, weekly, and monthly charts, and creating various trend lines, which can make trading easier.

This time, BCH happened to rise to 530 USD and then retraced down to 468 USD, which is a bit miraculous.

These lines were actually drawn a week ago; I just didn't know how to use them well, but gradually using them became more convenient.
